CHANNELlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 738,355, datedSeptember 8, 190B.

Application filed February 12, 1908. Serial No. 143,107. (Nomodcl.)

To @ZZ whom t may con/cern,.-

Be it known that we, ARTHUR DON PUER- NER and THOMPSON GRAY HEINE,citizens of the United States, residing at Butte, in the county ofSilverbow and State of Mont-ana, have invented certain new and vusefulImprovements in Channeling-Tools; and we do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the artto which it appertains to make and usethe same.

Our invention is an improved channelingtool especially adapted formaking outside channels for the soles of turn-shoes; and it consists inthe peculiar construction and combination of devices hereinafterdescribed and claimed.

' The 'object of this invention is to provide an improved tool of thischaracter in which the cutter is adjustable in two directions andadapted to .make a channel of any desiredA with alongitudinalguide-seat2, which is Open at its outer end. At the outer end and at oppositesides of the guide-frame are two pairs of gage-arms 3 4, which are atright angles to each other. The same are here shown as formed integralwith the guide-frame. The latter is provided at its inner end withasuitable stem 5, which forms the means for attaching the guide-frame toa handle 6. The cutter-bit 7 comprises an arnr, which is disposed to liein the guide-seat of the guideframe, is adjustable longitudinallytherein,

and is also adjustable in a planeat right an-A gles to its longitudinalaxis, and an armi), which is at right angles to and is disposed at theouter end of the arm 8. The outer portion of the arm 8 is formed on oneside with a cutting edge 10. The arm 9 has a cutting edge 11 on the sameside, the said cutting edges converging and being disposed at rightangles to each other. The arm 9 of the cutter-bit lies between the arms3 of the guideframe 1.` The arm 8 of the cutter-bit is provided near itsinner end with a longitudinaladjusting-slot 12 and is provided near itsouter end with a similar slot 13. The outer portion ofthe said arm Sisreduced in thickness on the side opposite the guide-seat ofthe frame 1,so that a certain degree of elasticity is imparted to the outer portionof the arm 8, which carries the arm 9. Au adjusting-screw 14 operates ina threaded opening with which theguide-frame 1 is provided,extendsthrough the slot l2, and bears on the outer side of the arm 8, itsfunction being to permit longitudinal adjustment of said arm S and toclamp the same iirmly to the guide-seat at any desired adjustment, henceenabling the chan-` nel cut by the tool to be of any desired width. Anadj usting-screw l5 operates in the threaded opening with which theguide-frame is provided, extends through the slot 13 of the bit-arm 8,is provided with a shoulder4 16, which bears against one side of thesaid arm 8 and is provided at its Outer end with a washer 17, whichbears on the outer side of the arm 8, and a clamping-nut 18, which bearson said Washer. It will be understood that by turning this screw thecutter-bit may be adjusted to cut a channel of any desired depth. Itwill be further understood that the two edges 10.11,'with which thecutterbit is provided, cut the two sides of the channel simultaneously,so that the same is formed in the edge of a sole at a single operationof the tool.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages ot' this invention.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-- 1. A channeling-tool having aholder provided on opposite sides with a plurality of angularly-disposedgage devices, and a cut- IOO ter-bit secured to the holder and havingangularly-disposed cutting edges, said cuttingbit lying between the gagedevices on opposite sides of the holder, substantially as described.

2. A channeling-tool having a holder provided on opposite sides, at oneend, with angularly-disposed gage-arms, and a cutter-bit comprising'angularlydisposed arms, each provided on one side with a cutting edge,said cutting edges converging, one of said arms of the cutter-bit beingsecured on the holder, and the angular'portion of said cutter-bit formedby the angulai` armsthereof being disposed between the gage-arms on therespective sides of the holder, substantially as described.

3. A channeling-toolcomprising aholder having a pair ofangularly-disposed gage arms on each of two opposite sides at itsouterend, a cutter-bit comprising a pair of angularly-disposed arms 'eachprovided on one edge with a cutting edge, said cutting edges converging,said cutter-bit being disposed with its angular portion between saidpairs of gage-arms, and means to secure one arm of said cutter-bit tosaid holder, said means having provisions for adjustment of said arm Iboth longitudinally and at an angle, substantially as described.

4. In a channeling-tool, the combination with a holding element, havinggage devices, of a cutter-bit having arms, each provided with a cuttingedge anddisposed at an angle to each other, one of said arms beingslotted longitudinally, forming a spring at its outer our hands inpresence of two subscribing wit- DeSSeS.
